Sellers of beauty products carrying uniform around explosive event (9)
I believe the answer is:
supernova
'event' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for supernova that I've seen before include "Exploding star that becomes much brighter" , "Star made brilliant by stellar explosion" , "Star that explodes and becomes extremely luminous" , "Star in decline" , "it puts an end to a starry career" .)
